[Q] backlight hack - Acer Iconia A500

i find myself using the tablet on lowest light settings all the time, without any trouble.
does anyone know of an app that would let me lower the backlight settings further than what honeycomb allows ?
battery use at 70% --;

I use an app called screen filter. It doesn't actually lower the blacklight but it does the trick.
Theres a couple other apps that do the same thing.

Fantastic! Tkvm ^^
This should appeease my quest for the st graal that is screen color inversion

Do you guys find this annoying? - Browser Brightness Setting

I want the Browswer to either,
1 - utilize the auto brightness function
2 - keep the brightness the same as what my setting is on
Is this that hard to do? why does the browser get it's own friggin brightness setting? At lease give us an option to take route 1 or route 2 on top of being able to change it.
Definitely something to think about in future roms.
And here is another example of why I despise auto brightness settings on screens. I like mine cranked all the way...except on my Sharp Aquos because that would lead to retinal bleeding at over 450nits
Just swipe from left to right along the notification bar to change the brightness to what you want.

i'd much prefer it automatically matching the brightness to the system setting. Hopefully, that will be fixed in the upcoming roms.
BTW, to increase screen brightness, turn Power Savings off in the Display settings. Doing this keeps the screen at 100% all the time --the browser and other apps will not dim the display anymore.

Very annoying. I have no idea why someone would do this. It makes no sense.

But having a auto for browser is basic setting in my mind though

But then you go outside and you can't see your screen because it's so low. This is specifically the reason it bugs me. I too love low brightness indoors but it sucks when you can't see the screen very well to turn it back up.
My only complaint is every page has to be white like a bright sheet of paper.
Back in the old days, computers had white text on black screens. Worked great at night or in dark rooms.

2.1 Screen Brightness

Two things regarding brightness I've found in 2.1 and wanting to know if I'm just missing something or what:
No more automatic brightness setting
The maximum brightness setting is about 2x as bright as the maximum setting on 1.6

Yes there is, through the widget with the wifi, gps and the other stuff.
Furthest to the right is a brightness icon that you can press to get auto brightness.

The middle setting is auto. In fact, Kindle even says 'To enable display brightness, turn off the automatic brightness adjustment in display settings.'
Mine does not ask a thing. Doesn't seem as auto option but a medium setting instead.

I have to say i miss that feature too. A lot. The middle setting is not auto. I downloaded Spareparts and enabled auto brightness but it does not seem to work. Not like 1.6 did anyway.

Hmm...did you actually put it infront of sunlight and check if the brightness automatically changes?
Alright everyone I was wary about the absence of the auto-brightness as well but I just did a test and I can confirm that the middle setting in the brightness setting on the power control widget is for auto-brightness. You can test this too by shining a bright light at the sensor, the screen brightness should INCREASE. Obviously a few of you mistook it for MEDIUM brightness which is understandable as the auto-brightness is between the minimum and maximum brightness under most circumstances, does that make sense?
Testet it with the Widget.
Seems to work. But in my opinion it worked better in 1.6.
Ah, good! Auto brightness is a critical feature IMHO.

I second that. Much better in 1.6. Here it does not even change. You barely notice it when going from inside to outside etc... I also tried on the Desire of a friend, and same thing. So 1.6 must have been better at that I guess.
Somebody can tell me how to disable the feature of automatic brightness, leaving it at the value I want, independently by the light? sorry if it has already been asked, but with the search function in the threads I can't answer it myself.
Hope somebody will help, because now my battery is drained too fast =(

How to decrease minimum backlight level?

Is there a way to decrease the minimum back-light level on a CM7 ROM?
I always prefer to keep back-light level as low as possible and not using automatic setting for it.
Recently I've tried one of the MIUI roms and noticed that the lowest back-light level on it is way dimmer that on CM7 ROMs. It allowed me to noticeably save on battery.
So is there any way to do it on CM7 based ROMs?
http://forum.xda-developers.com/showpost.php?p=14089317&postcount=10594
Tried and tested with typhoon rom. After usind this lib the cm7 autobacklight level should woork correctly..but therefore some LED Notification will behave a bit strange...you will be able to life with that. (=

not 100% as I use a CM mod (AMA), but check Settings / CM Settings / Display/ Automatic Brightness / Edit Other Levels

OK. I've tried it and saw absolutely no difference in minimum backlight level.
When I move the backlight level slider all the way down it is still on the same level
as with older libs. And it did break notification lights.
As I've mentioned before I am not using autobacklight at all. I just want to have manual backlight level go much lower.
There is a free app in the Android Market that will do just what you want. It's called Screen Filter. Using this app, you can set your backlight level very low, and even put a widget pre-set to your preferred brightness level on one of your homescreens.

This app is a fake. It does not decrease backlight level, but instead dims lcd pixels, which is not the same. Hence no power saving benefits. It would only help with OLED screens.

Did you replace lights libs to make it to work?

that's how it comes with AMA, which is based on CM7.1, so it could be part of the original CM (have no way to check as I don't use NAND builds)

Ah..I see. That is SD build.
OK. Looks like CM7 autobacklight works if I replace lights libs now (loosing LED blinking though). I guess I'll try it out and see how it turns out.
Thank you all.
One thing I've noticed that backlight level number is not very granular.
As there is no difference if I have it set to 1, 5, 10, 15 or 20. It only changes at 25

it might depend on the brightness ranges/thresholds - I've noticed in my build that if first two ranges are set as 0-100 and 100-200, the first one is ignored if upper limit is below 225, so I always get the screen brightness of the second range
I was looking for a dimmer lowest setting for the back light & tried Screen Filter BUT found it left the "black screen" well lit but everything else faded, almost like the colours were merging to gray rather than being dimmer.
Anyway, my need was for the clock display to be dim but found the Clock app's day/night mode button takes the clock display brightness right down low; lower than the manual screen brightness setting for sure... but only in the clock.
Hopefully any other noobs to Cyanogen / non-Sense ROMs may find this relevant! ;.)

[SOLVED] brightness hack?

How can I decrease the minimum brightness? The fire simply does not get dim enough for me to read books in bed.
Fully rooted.
I sometimes reverse the colors so that it is white on black while reading at night.
Try useing Display Brightness v.2.2 (from RubberBigPepper).
It gives you far better control of brightness in 1% incraments and it can adjust the brightness to a lesser level then the KF controls allow. By it's measurmement the KF controls only scale from 11-100%, so you can definatly get the screen dimmer and save power. Best of all this program will work on Non-Rooted machines and thereby becomes a must for all KF users.
Look for it in the market place or other locations as a sideloaded APK.
Enjoy!
On a rooted device, you can also use AdjBrightness (in the Market) or my RootDim (in the Market, Appstore and here). Both are free and will let you go one step below what looks to me like the 1% minimum setting of Display Brightness, to 0.4%.
On a non-rooted device, you can also use my paid ScreenDim (in the Market and Amazon appstore), which adjusts brightness down 0.4% and also has a separate contrast control.
But if you want the on-every-screen adjust bar, Display Brightness is the way to go.
Awesome guys! Thanks.
Edit: I could not get RootDim to keep the brightness after exiting the app even with SuperUser privileges.. Display Brightness works like a charm!

Ran across the same issue. This solved it for me:
Screen Filter
(search android market, as forum won't let me post the link)
Works great!, and it lets you add a custom widget to the desktop to dim and undim with a single click.

You might try DisplayBrightness. It puts a custom slider that is available on EVERY screen to adjust brightness down to 1%.

I don't have a rooted Kindle, so I can't test it. Is Safe Mode off? Have you tried setting the lock in RootDim?
RootDim, AdjBrightness and ScreenDim (and I have tested ScreenDim heavily on the Kindle Fire) will get you to a slightly dimmer level (0.4%) than the 1% Display Brightness does, though that probably doesn't matter to you.

Yeah, I tired the 'lock' setting, but did not work.
Actually I was thinking that below 1% might be necessary for my needs. I'll check those apps out.
I recommend flashing cm7 and using rendering in settings menu for a nice Retro red or green monitor effect!

You can also get that with ChainFire3D on a rooted device.

[Q] Schedule an app to run and close per time?

I'm looking for a decent app scheduler that can run an app by a set timed schedule?
I'm looking to start this screen dimming app (super dimmer), by a set schedule, around 8pm and to turn off at 6am.
The app itself does have an internal scheduler, but it does not work correctly, but the app works exactly as I need.
So what do I need to do this?
What exactly am i trying to do?
Well, I like the auto dimming feature of my phone, however at night, I do not like the lowest default dimming setting, I am comfortable with a much lower dim setting that Super Dimmer can provide. I basically want it to activate at sun down and deactivate at sun rise.
I would be even more interested in adjusting the phones default dimming ratio, if that is possible, if I can control and lower the auto dim setting in phone, that is preferable.
Taskbomb task scheduler?

I did install taskbomb before writing this post, is that what I want to use? I just have no idea how to configure it.
Tasker is awesome. You shouldn't even need to use a secondary app with it.
Sent from my MyTouch 4G using xda premium
Well looks like my idea did not work correctly. For some reason that program doesn't toggle on and off like I would need it to in order to work with taskbomber.
So this tasker app, does it allow for dimmer settings below the default android 0%? I'm looking for 200 levels.

I havent tried to myself, but it does have ability to ask for SU and device admin permissions so I bet it does.
I got it, tried it, it does allow for you to set lower than default values for some devices but for some reason it doesnt go as low as super dimmer did.......
Hmm I'm all out of ideas now!
